Qu-Pac to Cq-18T?

Has anyone made this move? I love my Qu-PAC but at 76 years of age it seems to get heavier every time I pack up for a gig. Pros/Cons would be appreciated. We are mostly a 2 person band but do use a BeatBuddy drum machine and a GR55 midi guitar setup. At most we need 8 channels but I do like having some room to grow if needed.

Thanks, Phil
